5.1 DESCRIPTION
Operation of Hale FoamLogix system is controlled by the Digital Display
Control Unit, provided with four push buttons (pads). (See Figure 5-1: “Con-
trol Unit Identification.”)
The Hale FoamLogix system constantly monitors the water and foam con-
centrate flow values, maintaining foam injection at the specified concentrate
injection rate. The system responds to variations in water flow by increas-
ing or decreasing the speed of the foam pump.
On initial power up of the apparatus, the Hale FoamLogix system begins a
brief self-diagnostic routine. When completed, the system enters the
STANDBY mode. The FLOW LED illuminates and the display shows the
current water flow rate in the monitored discharge pipe. (See Figure 5-2:
“Function Modes,” on page 123.)
Pressing the DISPLAY button (
i ) cycles through the four functions as indi-
cated by the red LED illuminating under each function (FLOW, %, TOTAL
FLOW and TOTAL FOAM).
